v 26, thelocking pin 22 Will be moved into or out of locking engagement with the recess 23 in the steering post.

The ends of the securing strap -9 and the heads of-the screws 31 and32 being Within the casing 3 and consequently the end of V 100i the strap cannot be' detached except from the inside through the opening nor can the lock casing be removed except by getting at the screws 31 and 32 through this opening. It is therefore important tovpro-' vide for locking the cap against .ren'ioval when-thellocl'ring pin is in engagement with the recess'of'the steering post. To provide for this locking of the cap,'the cap is provided on its inner side with an lnwardly L extending annular flange l0 provided with a recess 451 into Which the outer 'end of'the locking pin 22 extends when in docking po-' sition, thus locking the ca-p against-rotation, A recess 42 inf'the lockingpln near ts outer end is adapted to receivethefiange 40 when the locking pin is withdrawn from engage inent with the steering post but '1s notin I its extrenie rearwardposition. When in its extreme rearward position the portion of locked against removal when the locking pinv engage the the locking pin to the right of the recess 42 as shown in Figure 5L will be in position to from being rotated. The cap isthus, held 7 p is in looking "position and also when inoved to extreme rearward, position and the cap p 5 can be removed only Whenthe locking pin movedto this intermediate position only by useiof the key, the, lock casing cannot be is. in' 'intermediate "position-and as it can be opened by anyone not having :the key. The inner or floating tube 'l9'is pressed against the steeringpost by a coiled spring 43 which bears atone "end against the outer Q or; rear-end or this tube and at its outer end against the fiang'edO. I The lugs 20 and Qlofthe inner or floating tube 19 aiford an extendedbearing on the .7 steering post and are held in contact withthe pos t'by spring 5&3. r-By reason oft-he" r extendedbearing afforded by themythe lock pin is effectively prevented from being sprung out otthe recess in the steering post and itis made possible to use a locking pin o ii sn afller diameter than would otherwise be required andlof -course,'tomake the relockin A ftebtuahy preventing any possibility of bend ing or springing it out ofline" and-this tube 6 Whijcfhis supported in turn by the cess;2'3 or relatively small diameter. thus avoiding weakening the steering post.

*Thejinner or floating tube 19 supports the pin throughout its entire-length, ef-

i'nner or floating tubeis supported bythe casing 3 and bythe Wall-of the opening? in the housing 2;

' In order to apply the lock to an automobile, all that is necessary is :to borelthe flange a0 and prevent the cap L sha d,

curing it :tothe housing. a

0 enin .7 in the steerin 0st casin and the P a b P g recess 28 in the-steering post. The casing 3 is "then placed against 'the housing With the-inner end of tube 6 in the opening 7.

The strap 9, being previously secured at its end 12 by screw 13 is then brought around the housing and, the cap 15 being removed, is

.secured'by bolt 11. The cap is then screwed into place and the lock is ready for use.

The -rec'ess23 "in thesteering post may be so arranged that in order to bring it into "line with the locking pin, the steering w he'el will have to be rotatedto swing-the Wheels to :one side or the other orinto'any position which willrnake it impossible "to run the automobile for any appreciable distance without unlocking.
